Resource Sharing and Pipelining in Coarse-Grained Reconfigurable Architecture for Domain-Specific Optimization

Yoonjin Kim, Mary Kiemb, Chulsoo Park, Jinyong Jung, Kiyoung Choi

摘要:

粗粒度可重构体系结构旨在实现高性能和灵活性的目标。然而,现有的可重构阵列架构需要许多资源,而不考虑特定的应用领域。占用长等待时间和/或大面积的功能资源可以在处理元件之间流水线化和/或共享。因此,对于某些应用领域,可以在不降低性能的情况下有效地降低硬件成本和延迟。我们建议这样的可重构阵列架构模板和设计空间探索流程的特定领域的优化。实验结果表明,我们的方法是更有效的性能和面积相比,现有的可重构架构。

英文摘要:

Coarse-grained reconfigurable architectures aim to achieve both goals of high performance and flexibility. However, existing reconfigurable array architectures require many resources without considering the specific application domain. Functional resources that take long latency and/or large area can be pipelined and/or shared among the processing elements. Therefore the hardware cost and the delay can be effectively reduced without any performance degradation for some application domains. We suggest such reconfigurable array architecture template and design space exploration flow for domain-specific optimization. Experimental results show that our approach is much more efficient both in performance and area compared to existing reconfigurable architectures.
